Robinson, 35, was allowed up to the door of Number 10, where the Prime Minister lives, despite being a convicted criminal.

He said in a video: “We are here to deliver a petition of just under 200,000 people who signed to prevent a political witch hunt against members of our Armed Forces who I met at a service station. They had their photograph taken with me.

Robinson, whose real name is Stephen Yaxley-Lennon, still faces trial for allegedly committing contempt of court by disrupting a major grooming case.

He was accompanied by ex-Ukip MEP Janice Atkinson to deliver a petition after a group of soldiers were disciplined for taking a photo with the far-right activist last month.
